It is of course possible to make the rim 26 and the openings 28 in such a way that a special cap will have to be used but the rim and the openings are preferably such that the original cap can beused.

The locking mechanism which prevents the cap from being removed from the adapter, includes a locking plate 34 which may move in such a manner that the block 36 enters one of the openings 28. The block 36 prevents the fingers from registering with the opening 28 and consequently will prevent any of the other fingers which are anixed to the cap from registering in their openings. The block 36 is preferably a part of the locking plate 34 which is preferably curved to fit the inside of the adapter and is slidably fastened to the wall of the adapter by the fastening pinsor rivets 38 which pass through slots 40 in the plate 34 so that the plate can slide up and downto bring the block 36 either into the opening .28. or sufliciently below the rim 26 to permit the fingers 32 to pass over the top of the block 36 and pass out of the openings 28 when the cap is to bev removed from the container. The locking plate 34 is moved into either its locked or'unlocked position by the pin 42 which is operated from; the barrel 44 of the look, a slot 46 being provided in the plate 34 to permit the necessary.side movement of the pin 42 as the lock revolves. The lock barrel 44 which is shown is intended to be operated by a key,.although it may be operated by any other means such as are usually used with similar locks.

The cap 30 is locked on the rim of the adapter (which may be considered as the rim of the container) when the parts are in the position shown in Fig. 1. 1111011181 to remove the cap, the key is insertediin the lock barrel 44 and is turned, which operation moves the pin 42 downwardly. The movement of the pin 42 pulls downwardly the locking plate 34 and the block 36, whereupon the cap may be removed by twisting it until the finger pieces 32 registerwith the openings 28, whereupon the cap may be pulled directly off of the adapter.

The locks .which are used are preferably such that the locking operation is completed and the key can be withdrawn at a half revolution of the key so that the lock may remain in unlocked position in order that the cap may be used as an ordinary cap when desired and does not neces sarily have to be locked on the container. Thus, during the day the lock may remain in unlocked position so that the cap may easily be removed for filling the tank, but at night, when the car is in a public garage, the lock may be locked to preventaccess to the tank. However, the lock may be such that the key cannot be withdrawn from the'lock except when the lock is in locked position whereby the cap must always be locked on the tank. I v

' This application is filed as a division of my application for Locking closure, Ser. No. 441,488, filed April 4, 1930, which has become Patent No. 1,926,204, dated September 12, 1933.

From the above description it is apparent that various modifications of the invention may be made and it is therefore to be understood that, although a particular and preferred form of the invention has been described, it is recognized that many other and further modifications may be made and it is desired that the invention be construed as broadly as the claims, taken in conjunction with the prior art, may allow.

5. A device of the character described which includes, an adapter sleeve,.means for attaching said sleeve to a neck of a container, said means including a washer having tabs adapted to be bent over the edges of the openings in the neck of the container, a lower rim on said adapter and provided with a slot, a tab on said washer adapted to be received by said slot, said means also including a retaining bar extending under said lower rim for preventing unauthorized removal of said sleeve from the neck of the container, said lower rim being provided with a'compressible washer for preventing leakage from the container.

6. A device of the character described, which includes,"an elongated neck on a container, the "upper portion of said neck being provided with 'opening'a'a cap member for said neck, said cap member .being provided with fingers adapted to be received by'said openings in said neck, a looking plate slidably mounted on said neck, said locking plate being provided with a block adapted to enter one of said openings in said neck, a key operated'locking mechanism on said neck, and means whereby movementof said locking mechanism by a key moves said locking plate so that saidblock enters one of said openings in said neck and prevents removal of said fingers on said a 7. A device of the character described, which includes; anelongatedneck on a container, the upper rim of said neck being provided with spaced openings, a locking plate slidably mounted on said neck, said locking plate being provided with blocking means adapted to enter one of said rim openings on said neck, and a locking mechanism associated with said locking plate for moving said blocking means into one of said rim openings in said neck.

I 8. A device of the character described, including in combination, an elongated neck on a container, the rim portion of the neck being provided with spaced openings, a cap member for said neck and provided with fingers adapted to be received by said rim openings in said neck and locking means on said neck cooperating with one of said rim openings for preventing removal of said fingers on said cap member.

9. A device of the character described including in combination, an elongated neck on a container, the rim portion of the neckbeing provided with spaced openings, a cap member for said neck and provided with fingers adapted to be received by said rim openings on said neck, and locking means carried by said neck and adapted when operated to block one of the rim openings in said cap member for preventing removal of the said fingers on said cap member.
